Description

Technical Field

[0001] The utility model relates to the technical field of thread clamping, in particular to a thread clamping structure for a double-sided circular knitting machine. Background Art

[0002] A double-sided circular knitting machine is a knitting machine with two needle cylinders, including an upper needle cylinder (commonly known as a needle plate) and a lower needle cylinder, which are arranged vertically at 90 degrees. The main function of this machine is to efficiently weave various double-sided fabrics, such as ribbed and double ribbed fabrics. There are many types of double-sided circular knitting machines, some of which are special models such as ribbed machines, which are specially used for weaving ribbed fabrics. There are also ordinary double-sided large circular machines, also known as cotton wool machines, multi-functional machines or knitting machines, with a variety of needle channel configurations, such as (1+1) needle channel, (2+2) needle channel, (2+4) needle channel and (4+4) needle channel. Needle track, can weave and produce a variety of new knitted fabrics. In addition, jacquard double-sided knitting circular machine can weave double-sided fabrics with complex patterns. During the working process of the double-sided knitting circular machine, each needle cylinder has a set of needle seats for fixing the knitting needles. The needle cylinder is connected to the main drive shaft through a chamfered gear and is driven to rotate by the main drive shaft. When the main drive shaft rotates, the guide needle will follow the rotation and realize up and down movement through the transmission lever on the shuttle rod, thereby completing the weaving process of the fabric. The double-sided knitting circular machine is usually also equipped with a needle cylinder rotation control system for adjusting the speed and rotation direction of the needle cylinder.

[0003] A thread clamping structure with the public number CN219568216U specifically relates to the technical field of textile equipment, including a base, a movable groove is arranged on the top of the base, a transmission screw is connected to the inside of the movable groove in the horizontal direction, a servo motor for driving the transmission screw to rotate is installed on the outer wall of one end of the base, the transmission screw is a screw structure with opposite thread directions on the outer surfaces of the two ends, movable rods are connected to the outsides of the two reverse threads, and two clamping assemblies are connected to the tops of the two movable rods with symmetrical settings, and a control switch is arranged on the outer wall of the base. The utility model can effectively realize the clamping and loosening operations of the thread when in use, has a simple structural design, is easy to operate, and can play a buffering and clamping effect in the process of clamping the thread, and achieves the effect of adjusting the clamping force. In this scheme, when clamping the thread, the thread is easy to slip out of the range of the clamping assembly, which is inconvenient to repair and affects the clamping efficiency. For this reason, we propose a thread clamping structure for a double-sided knitting large circular machine. Utility Model Content

[0024] Furthermore, the inner length of the slot 8 is half of the upper end of the limiting column 9 , and the portion of the slot 8 that is larger than the limiting column 9 is the movable range of the limiting column 9 .

[0025] Furthermore, the upper end of the limiting column 9 is protruding, the lower end of the limiting column 9 is fixed to the upper surface of the base plate 1 , the limiting column 9 is fixed on the base plate 1 , and the upper part of the limiting column 9 is protrudingly installed inside the slot 8 .

[0026] Furthermore, an empty slot is provided above the lower mounting frame 6, the lower clamping wheel 7 is installed at the upper end of the empty slot, and limit blocks 10 are installed at both ends of the lower clamping wheel 7. The limit blocks 10 limit the range of movement of the silk thread to prevent the silk thread from slipping out of the range of the lower clamping wheel 7.

[0027] Working principle: the fixed column 2 fixes the position of the long board 3, and the motor 4 is turned on. The motor 4 drives the upper mounting frame 11 below to move downward, and the upper mounting frame 11 drives the internal upper clamping wheel 12 to move downward. The lower teeth 13 and the upper teeth 14 are installed in an offset manner to position the upper mounting frame 11 and the lower mounting frame 6. When the wire passes through, the wire exerts force on the upper clamping wheel 12 and the lower clamping wheel 7. The limit block 10 prevents the wire from moving within the operation range. The upper clamping wheel 12 is inconvenient to fix. The lower clamping wheel 7 drives the lower mounting frame 6 downward when subjected to force, and the lower mounting frame 6 drives the spring 5 downward to be compressed, thereby changing the distance between the two clamping wheels. The lower mounting frame 6 exerts force on the spring 5 according to the force size, and the spring 5 is compressed and expanded according to the force. The limit column 9 limits the range of movement of the lower mounting frame 6. The limit column 9 is fixed on the bottom plate 1, and the upper part limits the range of movement of the lower mounting frame 6 during operation.
